I don't have a problem with most of my socks, just the fuzzy ones made of somewhat slippery yarn.

And footies (the little socks that don't come up on the ankle too far) need to have a little pom-pom on the back to keep them from sliding past the top of the shoe and to the bottom of my feet.

I think most of my socks are stretchy with some sort of elastic thread woven in.
